Evaporative Canister

All models equipped with V8s, and 1973 and later 4- and 6-cylinder engines, have fuel evaporative emission control systems which include an evaporative storage canister. The purpose of this charcoal canister is to store gasoline vapors until they can be drawn into the engine and burned along with the air/fuel mixture. The air filter in the bottom of the canister should be replaced every 15,000 miles.
